PROTOCOL: Effectiveness of Educational Programmes to Prevent and Counter Online Violent Extremist Propaganda in English, French, Spanish, Portuguese, German and Scandinavian Language Studies: A Systematic Review.
Article in Campbell systematic reviews, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
This protocol outlines a systematic review that aims to understand the effectiveness of educational programmes, delivered both online and offline, designed to prevent and counter the effects of online violent extremist propaganda in multiple languages. The primary objective is to assess the impact of interventions on reducing violent extremist attitudes, beliefs and behaviours. A secondary objective is to identify key factors that influence the effectiveness of these interventions. Eligible studies will include randomised controlled trials and quasi-experimental designs that evaluate interventions, such as media literacy initiatives, counter-narratives, alternative narratives and gamified approaches. The analysis will synthesise outcomes using meta-analysis and narrative synthesis, concentrating on attitudinal and behavioural extremism measures. By addressing a significant research gap, this review aims to provide actionable insights for developing educational strategies to mitigate online extremist propaganda's spread, impact and radicalising influence.
